GREASE PACKAGE.

Application led November 25, 1922. Serial No. 603,183.

T 0 all whom t may concern:

Be it known that T, Louis W'. STEVENS, a citizen of the United States, residing at Marlboro, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in a Grease Package, of which the following is a specification.

This invention relates to the filling of grease guns and to packages of grease designed to be used for such purposes and known as refill packages.

Grease guns are now used very widely, particularly in the lubrication of various parts of motor driven vehicles. process of filling such a grease gun consists in scooping the grease out of the container in which it is purchased, either with the fingers or with some implement, and ladling it into the gun. This obviously is a dirty operation and it is also unsatisfactory for the reason that it is almost impossible to fill the gun in this manner to more than half or two-thirds of its capacity.

The present invention aims to devise a grease package which can be manufactured as economically as present packages, and with which the filling of a grease gun can be accomplished expeditiously and conveniently.

The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claim.

'Referring now to the drawings,

Figure 1 is a perspective view of a grease package embodying the present invention certain parts thereof being broken away; and

Fig. 2 is a view, partly in side elevation and partly in cross section, showing the manner in which a grease gun is lled by the use of such a package.

The package shown comprises a tubular shell 2, preferably made of sheet metal and of approximately cylindrical form but hav- The usual ing a short reduced end portion 3 joined to the main body of the shell by a shoulder 4. The opposite ends of this shell are closed bycovers 5 and 6, respectively. Certain of the dimensions of the container are governed by the dimensions of the gun in which the grease is intended toy be used. That is, 56 the reduced end 3 is made of the proper diameter to fit snugly in the end of a grease gun body 7, and the shell 2 is made of the proper internal diameter to enable the piston 8 of the grease gun to fit in it.

This container is filled with grease at the refinery, or at any other convenient wholesaling plant, and it is then handled in commerce exactly as are the present grease packages.

According to the preferred process of filling the grease gun, the cap 9 of the gun is removed and the piston 8 is taken out of the barrel or cylinder 7 of the gun. The caps 5 and 6 of the grease package are then re- 70 moved from the shell 2, andthe reduced end 3 of the shell is inserted in the open end of the gun, as clearly shown in Fig, 2. The piston 8 is next inserted in the opposite end of the shell 2 and it is then forced almost 75 through the shell until it brings up on the shoulder 4, thus ejecting the grease from the shell and forcing it into the gun 7. It is preferable to have the discharge tube at the opposite end of the gun disconnected, or 80 at least open, while this operation is being performed, in order that the air may escape freely from the gun as it is displaced by the incoming grease. When the shell 2 hasbeen emptied in this manner, the piston 8 is with- 85 drawn from it and the shell is thrown away. The piston then is reinserted in its proper position in the gun cylinder 7, the cap 9 is screwed in place, and the gun is ready for use.

It will be evident that by the use of this package fthe gun may be filled quickly, cleanly and conveniently. Furthermore, the grease gun is filled completely. The packaging of grease in this manner is fully as 95 economical as the methods of packaging heretofore used, While the packages provided by this invention are far inore convenient for the ultimate consumer to use.

Having thus described my invention, what 5 I desire to claim as new is:

A refill package for grease guns comprising a Shell of substantially cylindrical forni iilled With grease and having one en d thereof open for its entire diameter, a removable cover closing said end,'said shell being reduced slightly in its internal diameter near its opposite end to provide a shoulder adapted to fit against the open end of a grease gun With said reduced portion entering the end of the gun, and a removable cover closing said shouldered end of the shell.
